Brighton & Hove Albion defenders Lewis Dunk and Shane Duffy have signed new five-year deals at the club, keeping them at the Amex Stadium until June 2023.
Youth-team graduate Dunk has made more than 200 appearances for the Seagulls, while Duffy joined from Blackburn Rovers for a then club-record fee in August 2016.
Albion boss Chris Hughton said: “I am delighted for both Lewis and Shane.
"They have been terrific players for the club, helping us win promotion and establish ourselves in the Premier League last season.
“They have formed a very good central defensive partnership, and have played a really important role in what we’ve achieved.
“Both are vital members of the squad, and it’s very pleasing that they’ve committed their long-term futures to the club.”
